the question is when is the variable you want to append available to the
javascript.
as soon as you get the variable in the javascript the next thing you can do
is append
it to the value of the href attribute of the <a> tag.

<html>
<head>
<script type="text/javascript">
window.onload = function() {
var someLinkHref = document.getElementById('someLink').href;
someLinkHref += "&anotherVar=8";
alert(someLinkHref);
}
</script>
</head>
<body>
<a id="someLink" href="http://somesite.com?a=5">
click here
</a>
</body>
</html>

if you want to use the onclick event handler as rob suggested, you could
stash the variable in the Window
global object, then reference it in the implementation of the onclick
function (though i still have mixed feelings
about that approach [the Window object part that is]).

Your example worked very well to provide an alert showing exactly
what I needed to be in the href string. However, it didn't work to
actually alter the actual link href string -- even when I commented
out the alert. IOW, it remained:

<http://somesite.com?a=5>http://somesite.com?a=5

instead of:

<http://somesite.com?a=5>http://somesite.com?a=5&anotherVar=8

I like the idea of keeping the code unobtrusive and working as it did
-- I just need it to work as a link.

Any ideas? This is so close.

Cheers,

tedd

Tedd, try this (it's also live and working at
http://www.crusar.org/test.php):

<?
$s = $_GET['s'];
?>
<script language="JavaScript">
function writeHREF(value,title) {
var url = "http://www.crusar.org/test.php";
var currentTime = new Date();
var month = currentTime.getMonth();
var day = currentTime.getDate();
var year = currentTime.getFullYear();
var jsvalue = month + '/' + day + '/' + year;
document.write('<a href="' + url + '?s=' + value + '&jsvalue='
+ jsvalue + '">' + title + '</a>');
}
</script>

This is where your JS link will appear, Tedd:
<script language="JavaScript">
writeHREF('<?=$s;?>','Test Link');
</script>

This might be a way to do it:

*Example 1*
<script>
function appendMeBaby(aVar){
self.location.href = 'img.php?s=' + aVar +
'&someOtherVar=itIsMeTheValue';
}
</script>
<a href="javascript:appendMeBaby(<?php echo($value);?>);">Click here</a>

*Example 2*
<script>
function appendMeBaby(aVar, bVar){
self.location.href = 'img.php?s=' + aVar + '&someOtherVar=' + bVar;
}
</script>
<a href="javascript:appendMeBaby(<?php echo($value);?>,
'itIsMeTheOtherValue');">Click here</a>

Hope this helps

strange; i missed that when i put it together; my bad, it was late.
here is a revision that works.

<html>
<head>
<script type="text/javascript">
window.onload = function() {
var someLink = document.getElementById('someLink');
someLink.href += "&anotherVar=8";
alert(document.getElementById('someLink').href);
}
</script>
</head>
<body>
<a id="someLink" href=" http://somesite.com?a=5">
click here
</a>
</body>
</html>

the problem was the local variable was being assigned the value of the
attribute, not the reference
to the tag in the dom. i have now set it to be a reference to the variable
in the dom.

I don't believe that is standards-compliant use of the href attribute.
Also it doesn't degrade gracefully for people who have JavaScript
disabled.

Daniel

That's slick.

I solved the problem by using:

<a href="img.php?i=<?php echo($value);?>" onclick="window.location =
this.getAttribute( 'href' ) + '&s=' + s; return false;">

But, I am sure I will be using your's sometime soon.

Thanks,

tedd

Not that I provided information otherwise, but
document.getElementById won't work in this case because there are
several links involved. As such, I have to use
document.getElementByClass and that has problems.

Unfortunately, my solution isn't unobtrusive.

<a href="img.php?i=<?php echo($value);?>" onclick="window.location =
this.getAttribute( 'href' ) + '&s=' + s; return false;">

However, I couldn't see a way to make it so.

Many thanks for your time and effort.

Why not? I'm guessing because you need to the link to have the
JavaScript variable in it. If this is the case then the href target
should link to a page informing the user that they need to have
JavaScript installed. By doing so you inform them of why clicking on the
link is not having the desired outcome :)

Cheers,
Rob.

Rob:

I would agree with you IF I was creating a web page for the general
public. However, what I am creating in my laboratory is a monster of
my own making that will be used only by my clients AND those clients
will be required to have javascript turned on.

Sometimes, programming for the lowest common denominator limits possibilities.
